PSI and JIR high level functions will fail first time they're called with a "try-error", but work subsequently

[ChristopherWilks]

I've seen PSI and JIR fail, the first time they run and then work subsequent times on the same input SQB objects. Maybe this is some initialization issue since it only appears to happen the first time the jir/psi function is called?

Error:

Error in as.data.frame.default(x) :

This could also be tied to running the queries in parallel. I have gotten of the code that does so.

I agree, looks like they're both working now the first time, thanks!
